Get Started and Keep Going with PowerFrame

A new manufacturing process has led to Varta batteries with greatly improved cold starting energy, a longer working life and increased reliability. This new process involves the manufacture of the battery’s positive grid, and the manufacturer of the Varta range, Johnson Controls, reports that the implementation of this technology, which it calls PowerFrame, ensures consistent and stable positive grid quality at all times. PowerFrame technology has now been applied to the company’s Silver, Blue and Black Dynamic battery ranges.

The benefit for the consumer, says the Varta manufacturer, is an improvement in all critical aspects of car battery performance at no additional cost. Going into the nuts and bolts of the technology, Johnson Controls explains that without a frame on all four sides, traditional ‘expanded’ technology battery grids have an irregular, weaker structure, whereas the PowerFrame design provides a stable and complete framework to minimise grid growth, corrosion and prevent short circuits – all of which leads to longer service life. To achieve consistently higher starting power through maximum current flow in the PowerFrame range, more lead is used where electrical current is greatest, enabling faster recharge acceptance and optimal conductivity.

The high precision punching process now used by Johnson Controls in the manufacture of all Varta-branded car batteries also reduces grid corrosion, which previously led to the alloy plate becoming brittle, to a minimum. The cleaner and more efficient production process employed is also said to be environmentally beneficial.

The Silver, Blue and Black Dynamic battery ranges incorporating PowerFrame grid technology are available through a network of more than 500 Varta specialists in the UK.
